Plugin suggestion

Good day everyone! Please help me to find for a plugin that I'm looking for! So I want to make custom adventure map where I can set spawnpoint, endpoint, some mobs that's needs to be spawned by some triggers (many amounts of mobs). It's needs to something similar like an every level of Left 4 Dead. So the whole event is -you spawned, passing through to endpoint and killingmobs along the way. Thanks in advance!
